DEVICE FOR COILING WIRE.

SPECIFICATION-forming part of Letters Patent No. 229,915, dated July 13,1880.

Application filed March 3, 1880.

To all 'whom it may concern Beit known that I, CHARLES D. ROGERS, of thecity and county of Providence, and State of Rhode Island, have inventeda new and useful Improvement in Machines for Drawing Wire; and I dohereby declare that the following specication, taken in connection withthe accompanying drawings, forming a part of the same, is a full, clear,and exact description thereof.

My invention relates to wire-drawing machines which employ a revolvingdrum upon which the wire is coiled as it leaves the drawplate; and myimprovement consists in combining with the winding-drum of suchmachinery suitable means for stripping the heavy coil from thewinding-drum and bringing it to such position that it can beconveniently handled for removal from the machine.

I am aware that machines for making wire ferrules have heretoforepossessed the capacity of. cutting off a length of previously-coiledwire and of discharging the length so cut oli' by the retreat of itssupporting-arbor 5 also, that in other machines for the same purpose thewire has been coiled upon an arbor to form the ferrules, and the outerend of the coil forced gradually beyond the outer end of said arbor,because of the ceiling of the wire upon the arbor at the opposite end ofthe coil and against an abutting surface, and that when aferrule hasbeen cut from the coil thus formed said ferrule could drop freely fromthe end of the arbor.

I am also aware that in machines for coiling rods and wire the reelsthereof have been provided with stripping devices, whereby, when thereeling operation is completed, the coil of rods or wire may, through ahand-lever, be pushed from the horizontal supporting-pins of the reeland the coil allowed tofall upon its edge. So far as my knowledgeextends, however, no wire-drawing machine prior to my invention was everprovided with means whereby the coil of drawn wire upon vthecoilingdruln could be lifted mechanically above said drum, nor anymachine provided with means of any kind for facilitating the labor ofdisengaging the coil of drawn Wire from the drum (No model.)

upon which itis tightly Wound under the heavy tension always incident tothe drawing operation.

Referring to the drawings, Figure 1 shows a top view of a coiling-drumembodying my improvement; and Fig. 2 represents the same in elevation, aportion being cut away the better to show the parts.

The coiling-drum A is of the usual form, and is mounted upon thedriving-shaft B, so as to rotate therewith. This drum is provided withvertical slots a, to receive and guide two or more arms, C, which arehinged to a collar, D, secured to the shaft B, and the iiange A of thedrum is grooved, as at a', to receive the ends of the said arms, therebyallowing the coil of Wire t'o rest upon said iiange and above the planeof the ends of the arms.

Loosely mounted upon the shaft B, and within the drum, is a cylindricaldisk, which is slotted in spiral lines, as at e. The hinged arms C passthrough these spiral slots c, the faces of which slots act as cams uponthe arms when the disk E is rotated and raise them, as shown in dottedlines in Fig. 2.

rEhe rotation ofthe disk E, and consequent raising of the arms C, iseffected by turning a crank, F, which is mounted on the vertical wall ofthe drum, and is connected with the disk E bymeans ofjointed linksff,asshown in Fig. 1.

The operation ofmy improved device is substantially as follows: Adesirable amount of Wire having passed through the draw-plate and beencoiled'upon the drum A, the ends of the wire are secured to the body ofthe coil, which rests upon the flange A andabove the outer ends of thearms C. The crank F is then turned toward the center of the drum, whichcauses a partial rotation of the annular disk E, and consequently thearms C are made to ride up the faces of the respective inclined planes eto the elevation indicated by dotted lines in Fig. 2. A further rotationof the annular disk E to a small extent causes the slots c to run clearof the arms C, when the latter will be supported in their elevatedposition upon the top edge of the disk E.

It is obvious that the coil of wire will be stripped by the arms fromthe winding-drum and brought to a position where it can be easilyhandled for removal.

After the coil of wire has been removed the crank F is returned to itsoriginal position, causing the disk E to revolve in the oppositedirection and the arms C to pass into the slots c and be lowered, whenthe drum will be again ready to receive wire from thc draw-plate.

Although I have shown and described a crank and arms connected with thedisk E for I the purpose of partially rotating said disk, I

am aware that the base of the disk may be a gear, and that a pinionmeshing with said gear may be secured to the crank-shaft for the purposeof moving the disk, and thereby raising the arms. I am also aware thatthe disk may be dispensed wit-l1, and a loosely-mounted gear having camsor inclined planes upon its surface be used in its place.

Having described my invention, what I claim, and desire to secure byLetters Patent,

1. In a wire-drawing machine, the combination, substantially asdescribed, of the ceilingdrum, two or more arms projectingontwardlybeyond the vertical wall of said drum, and

2. In a wire-drawin g machine, the combination of the slottedcoiling-drum, the drivingshaft for the same, two or more arms passingoutwardly through said drum, two or more cams loosely mounted on saidshaft, and suitable mechanism for causing a partial rotation ot' saidcams, substantially as described.

3. In a wire-drawing machine, the combination of the slotted(soiling-drum, the drivingshaft for the same, two or more arms passingoutwardly through said drum, an annular disk loosely mounted on saidshaft and provided with cams, and suitable mechanism for partiallyrotating said disk, substantially as described.

4. The combination of `the slotted coilingdrum A, shaft B, hinged armsC, mutiple camdisk E, and rotating mechanism F ff', substantially as andfor the purpose specified.

CHARLES D. ROGERS.
